cabal-version: 2.2 name: streamly version: 0.9.0 synopsis: Dataflow programming and declarative concurrency description: Browse the documentation at https://streamly.composewell.com. . Streamly is a streaming framework to build reliable and scalable software systems from modular building blocks using dataflow programming and declarative concurrency. Stream fusion optimizations in streamly result in high-performance, modular combinatorial programming. . Performance with simplicity: . * Performance on par with C () * API close to standard Haskell lists () * Declarative concurrency with automatic scaling * Filesystem, fsnotify, network, and Unicode support included * More functionality provided via many ecosystem packages . Unified and powerful abstractions: . * Unifies unfolds, arrays, folds, and parsers with streaming * Unifies @Data.List@, @list-t@, and @logict@ with streaming * Unifies concurrency with standard streaming abstractions * Provides time-domain combinators for reactive programming * Interworks with bytestring and streaming libraries homepage: https://streamly.composewell.com bug-reports:
